How Can I Speed Up My CDK Stack Deployments?

Consider implementing caching in your CI/CD process. I switched from CodePipeline to GitHub Actions and saw a dramatic reduction in deployment time—around 40% faster!

In CDK, only the changes should trigger recompilations and rebuilds, so try to keep your stacks separate instead of nesting them. Keeping things separate can significantly improve your deployment efficiency!

There's an option to define how many stacks to deploy simultaneously. If your dependencies are all sorted, you can deploy multiple stacks at the same time, which can speed things up quite a bit.

Check out the new timeline view in CloudFormation to see what's causing the slowdowns. CDK should only redeploy resources that have changed, so if you're making lots of changes during deployments, that could be the culprit. Typically, serverless resources deploy faster, so you might want to lean towards those if possible.

Going for multiple stacks might not be the best route; they can lead to circular dependencies and slow everything down. Instead, try organizing your resources into constructs rather than stacks.

One way to speed things up is to decouple your stacks and eliminate any nesting. Instead of nesting them, you can pass values between stacks using the SSM Parameter Store or use cross-stack references. This can help reduce complexity and improve deployment times.
